I conducted an A-B test with the BCD536, which won (although even that scanner does not pick up the BWI ATC the ICOMs receive). Interestingly, both Unidens had the same limited reception until I

Comparing a whip on a desk to an antenna in the attic is not necessarily a valid test. I have Hardy board siding, which proves to be an excellent RF shield (it's made of concrete, in part).

A good point; didn't consider it, since I don't have airbands programmed into the 536 (using it for local P25 Phase 1 public service). Will program in a conventional airband system and conduct an A-B

Obvious question: How does the 15 compare to the 536? If there is much of a difference, I would say there is an issue with the 15. S-meters, while they at one time were reliable indicators (pun

Interim Report: I tried different multicoupler ports and even the discone feeding 15X directly; as expected, the same results. A signal must be at least S7 on the ICOMs in order to break minimum

*Hi, I have about 5 different units covering several frequency ranges of the Stridesberg Engineering Multicouplers for many years. There are non-powered or 12vdc powered versions. They produce the

I have a Stridsberg multicoupler, it’s amplified. I find my 536 works better with the supplied whip antenna than with the discone on the multicoupler. I think the multicoupler overloads the

well, if you have attached the antenna directly to the radio (eliminating the multi coupler and the other radios) amd reception did not improve would that not point to the radio being the likely

No difference trying other output ports on the multicoupler. Unlike a signal splitter, an active multicoupler provides uniform amplification and isolation of all output ports to neutralize signal loss

Said this 3 times now….but we get no result. mike

You may want to try a LNA to boost the signal level. Each splitter device connected attenuates the signal level. Matt (via iPhone)

First of all, sorry about the fire. I hope everyone in your family, including pets, are OK. I would stay with the 536 or upgrade to the latest technology, the SDS-200. Mike

SDS200's Joel R Kahn

why not couple the 15X directly to the antenna and see if reception improves?

Switching to Ubuntu does nothing to solve the problem of running Sentinel.

Yes, they are insured. 1 & 2 years old. Tim

One SDS200, one BCD536HP. Both radios have their pros and cons, so with both you get a great system

SDS200s for an upgrade, or new 536s. Joe M.

No question SDS 200

Uh? But new ones? Are they insured? 73, Gary
